IMPROVEMENT IN STEAM ENGINES.

"lO ALL WHOM I'l MAY CONC-EEN:

Be it known that I, JOHN L. LAY, of the city of Buffalo, in the countyof Erie, and State of New York, have invented cert-ain improvements inthe Method of Supporting the Cylinders of Vertical Steam Engines; and Ido hereby declare that the following is a full and exact descriptionthereof, reference being had to the accom` panying drawings, making partof this specica-tion, in which- Figure 1 is a side elevation of' a high'and a low-pressure cylinder, arranged vertically, with the supporting'frame partially in section.

Figure?. is a horizontal section in the plane of the line z rv, fig. l.

Figure 3 is a modification of my improvement.

Like letters designate corresponding parts in all the figures.

My invention consists of the means hereinafter described of supportingthe cylinders of vertical engines.

In the drawings, A A represents three or more standards firmly fastenedto a base-plate, B, preferably by bolts through flanges a at their foot,which converge or incline towards each other at the top, their upperends being secured to a cap orhorzontal fra-me, C, as'shown in fig. 1.These standards I prefer to make of iron, (although other material maybe employed,) of the angular form shown by the cross-section in fig. 2.To these standards are bolted brackets D D, the arms-of which projectinward and support the cylinder E which rests upon them, as shown infigs. I and 2, being bolted o1' otherwise fastened thereto. Under theends of each of the brackets I employ a vertical post or column, G,which renders the support more firm where the cylinder is of large size.F represents the high-pressure cylinder, cast with three or more flangesgg (fig. 1)wl1ich rest upon and are bolted to the top of' acorresponding number-of standards I-I H, similar to A A, which arefirmly bolted to the eapplate C, as shown. The cylinder E may beprovided with flanges similar to those of a high-pressurecylinder, andbe bolted to the brackets D, or it may be east with a flange, g,surrounding it, and be arranged within and bolted to the top plate C offrame A A, as represented in fig. 3. If preferred the ends of thebracket-arms may be connected by an annular plate, upon which restsandis fastened the cylinder, the columns being employed as represented,the eifect being substantially the same as when-the brackets aredisconnected from each other, the flange4 of the cylinder in that caseperforming the same office as theannular plate. It is evident that thestandards A may be made sufficiently high to supportIthe cylinder F attheir top, while the cylinder E is sustained as represented in iig. 1.`This arrangement of the converging standards and their adjuncts givesgreat steadiness and stability to the engine hy bracing it equally inevery direction, and obviates much oi' the jar and vibration which havean injurious effect on engines of` this construction, where a single rodcarries the two cylinders placed in a line. It also admits of their moreconvenient adjustment to a true working line than when otherwisearranged and supported.

What I claim as my invention isframe for supporting the cylinders E F ofvertical compound engines, composed of the converging standards A A andH II, cap or intermediate plate C, fianges g g, and brackets D D 0requivalent, with the pillars G G, combined and arranged substantially inthe manner and for the purpose set forth.

In witness whereof I have hereunto signed my naine in the presence oftwo subscribing Witnesses.

JOHN L. LAY.
